PLUMBING SYSTEM
DRAINING THE FRESH WATER SYSTEM
Permanent water tanks may be drained through a valve located near the tank. A recreation
vehicle with a demand pressure pump system will have low-point drains attached to the
water lines (normally located near the water tank).
These low-point drains will release water in the supply lines by opening the valves and all
faucets. The water heater has its own drain plug. To drain the permanent fresh water holding
tank and supply lines:
1. Turn the water heater power OFF (Turn off the Electric & LP GAS switches).
2. Open all faucets, including the outside shower faucet.
3. Open the “fresh tank drain” valve. All permanent fresh water
tanks can be drained by one of two types of drain valves. A white
plastic drain is attached to the exterior wall (open valve to drain)
or a valve located inside the motor home adjacent to the water tank
(this knob turns 45° to open or close).
4. Open the “low point drains” by turning, then pulling the handles
up. As their name indicates, they will be at the lowest point of
water lines. A label is placed on the outside of the RV to indicate
where the drains are located. The drains will typically need to
be opened from inside the motor home. Once the label is found

5. Drain the sink by removing the drain cap.

9. Relieve the water pressure using the P&T valve BEFORE removing the water heater
drain plug. If there is any water pressure present the water will spray out of the opening
when the drain plug is removed.
